Description

Rechargeable hybrid battery/surpercapacitor system
Background of invention
The present invention relates to chargeable electric energy storage system many times, for electric application apparatus widely provides reliable power supply.The invention particularly relates to a kind of rechargeable storage system, it expresses the high-energy-density relevant with battery usually, and the high power density of ultra-capacitor representative and long service live.
In the present invention, this type systematic is a kind of energy storage device structure of multilayer, comprise many positive poles and negative pole element, each both positive and negative polarity element comprises dummy capacitor or double-deck ultra-capacitor material and the rechargeable insertion battery material that constitutes a monomer flexible structure, the size and shape of monomer flexible structure can determine as required, with the most compatible, and provide favourable high-energy-density and power density with application apparatus.
Modern Application needs removable power supply, and these application spread all over electric automobile from personal telecommunications apparatus, and quantity is index to be increased.These requirements that are applied on voltage for example or the power level are extensive, can provide high-energy-density rapidly in long-time always and can recharge light storage facility to the operating energy level very soon but all prefer to.So far, any in two kinds of existing type storage facilities, promptly such as rechargeable batteries such as lithium electronics insertion systems, the perhaps double-deck response type ultra-capacitor of induction type pseudocapacity ultra-capacitor or non-induction type, what satisfy these demands of removable energy widely.
Select battery or ultra-capacitor system usually by described application to high-energy-density or carry which more urgent deciding of high-power demand rapidly, wherein battery has high-energy-density, and ultra-capacitor can be carried high power rapidly.Battery in single application, meets high-energy and develops in some cases in the following manner with the trial of two kinds of demands of high power density two kinds of device kinds are arranged in, so that can charge to ultra-capacitor between the time period of high power requirements.Clearly, the shortcoming of this kind example is a preponderance.Other restriction of this example is reflected in the time demand of battery charge, and the diversity of battery and battery life cycle, and the physical property critical conditions of wherein inserting the battery charge operation can shorten battery life cycle usually.
System representation of the present invention goes out, and the device that meets removable electric energy application demand has tangible progress, and it is a light weight and enlarge and to combine the two necessary characteristic of battery and ultra-capacitor in the monomer integrating device of electric capacity.When system for example has can insert the comparative electrode that the battery pack compound forms by an activated carbon ultra-capacitor element and one time, be a kind of transition metal oxide spinel at described compound especially, its structure can be carried out the rapid diffusion of ion and be inserted under the few situation of back physical distortions, and this system can have the high energy storage ability of battery and the high speed energy delivery and the beat all life cycle of ultra-capacitor simultaneously.Induced cell inserts the unique combination of charging with capacitive surface and has another advantage, can realize such insertion system, they just can be reached because can for example adjust the held comparative electrode material rareness with quite big or small cation (for example, alkaline earth cation) size.
Hybrid system of the present invention can use previous rechargeable to insert most of composition of battery and ultra-capacitor device.These earlier device typically are described in for example United States Patent (USP) 5,418,091 and 5,115,378.As in these early stage systems, that inserts that electrode can comprise metal sulfide, oxide, phosphoric acid salt and fluoride, open architecture contains carbon graphite, hardening carbon and coke, and alloying element, such as aluminium, tin and silicon.Similarly, surface-active capacitor material, normally high surface area enclosed construction activated carbon powder, foaming body, fiber and textile, they can be used in the comparative electrode.The wherein active electrolyte element of hybrid system can be allocated by current material equally, and in the non-aqueous solution that can insert alkali metal and alkaline earth metal cation, use specific utility, this material is included in the material of fibre-bearing or polymer substrate with tangible fluid form usually, is the environment of a conducting of mobile maintenance of two kinds of electrolyte ion materials thus.The stacked polymer layer format description of secondary cell representative is in United States Patent (USP) 5,460,904, and relevant publication is applicable to structure of the present invention very much.
